Fun hiking, tons of trails to choose from to match your skill level. Trails are very well marked and maintained.

Easy fun trail to do without thinking! Just some exercise

The hike itself is ok, but as others have mentioned, the “view” is underwhelming and does not make for much of a destination. Opt for the Big Tree Ridge Trail instead if you want a truly stunning view from Cougar Mountain. Also, the only moderate section of this trail is the somewhat steep decline to the so called lookout. This can easily be bypassed by continuing down the main trail and then traversing .1 mile to the lookout. Traverse back and finish the loop.

Easy hike/walk. Not crowded, but got there early. Beautiful waterfall-ish. Not crowded.

A very nice area for hiking. Very easy system and nicely marked.

Nice hike through the woods. When I got there (Monday) the parking lot was packed, but there are so many routes and trails in this park that the trail I was on was uncrowded! Really enjoyable waterfall and creek. No views, but I really enjoyed my walk. Nice and peaceful. Will return to do Long View Peak in a few weeks.

Nice quick hike with a waterfall in the middle.

Lovely winter - early spring hike. Lots of open sky on a sunny March day before the maples and alders leaf out. Busy in the first/last mile near trailhead.

Great Hike with kids. Beautiful creeks on the way

It’s a great trail but if you’re paying really close attention to the signs, you’ll wander off onto one of the dozens of other trails running through Cougar Mountain and you’ll be there for much longer than you planned. Very kid friendly, saw plenty of families while I was there with kids even as young as toddlers.

Steep sections lead to a fantastic waterfall and a trip next to a talkative creek.
wheel chair friendly doesn't apply to this trail at all

Lots of folks on this trail.

Beautiful snowy day cleaning up after dog owners.

Great for kiddos and pups. Parking a little tricky when busy.

Great loop for taking a kid on a hike or running. Waterfall was strong in January.

My 4 & 5 year old both walked the whole loop! The waterfall was gorgeous. Although parking is a beast, the trail was not packed. We’ll be back!

Nice view but small view point and trees block view little

I couldn't neccessarily find the De Leo Wall trail because tho it was marked on the map, there was no "you are here" point. Also, none of the trails were marked De Leo Wall.
However, this was a fun little hub of interconnected trails.

Great forest trail. Some up and down, but not overly strenuous. We took our 6-month old in a backpack carrier and it wasn't too hard. Waterfall was a nice surprise.

Went over the summer, and the hike was eclipsed by how buggy it was. Very pretty, though.

Nice walk in the fall, even after rain. The road is still not that wet. One thing to remember is the viewpoint is nothing but a small platform with little view to Renton direction thru trees. And if you continue after the view point, make sure you do not turn right into a way to local community. Always check GPS for right turns.

Nice walk; lots of twists and turn, good change in uphill/downhill,

There were others on the trail, but it didn't feel busy. Even though it is close to neighborhoods, it feels remote.

Was great but many folks had their dogs off leash which was frustrating when you have a nervous dog.

Nothing to see. Falls dried up.

The view is normal.

Very lightly trafficked on a Saturday morning. Saw a really cool snake. Trails are marked properly and well. No views except for the tall beautiful trees.

There are many interconnected trails that allow you to expand your hike and explore the other parts of Cougar Mountain.
